A rotary actuator for a bicycle handbrake is characterized by a housing connected with a bicycle handlebar and an actuator rotatably connected with the housing. The actuator has a handle which extends radially from the axis of rotation of the actuator. A brake cable is connected with the actuator so that when the actuator is rotated in one direction, the cable is pulled to squeeze the brake calipers against the rim of a bicycle wheel, and when the actuator is rotated in the other direction, the cable is pushed to release the brake calipers. A releasable locking mechanism between the actuator and the housing is operable to lock the actuator in a brake release position and to release the actuator for rotation to apply the brake.
